- FIRE-BOX.

SPECIFICATION forming part of Letters Patent No. 261,105, dated July 11,1882,

Application filedApril 18,1882. (No model.)

To all whom it may concern:

Be it known that I, OYRUs K. VILAS, of Alstead, in the county ofCheshire and State of New Hampshire, have invented a new and ImprovedFire-Box, of which the following is a full, clear, and exactdesoription.

The object of my invention is to provide a new and improved fire-box forstoves and heaters from which the ashes and clinkers can be removed veryconveniently.

This invention relates to an improvementin fire-boxes of that classadapted to r'evolve and to be used either end downward or as a grate;

and it consists of a spherical or globe-shaped chamber or box providedwith apertured or slotted covers covering opposite openings therein,combined with a stove or heater havingan opening in its bottom providedwith beveled edges, substantially as hereinafter more fully set forthand claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a cross-sectional elevation of a stove provided with myimproved fire-box. Fig. 2 is a plan view of the fire-box, showing itdetached from the stove.

The fire-box A is made of cast metal orother suitable material, and inthe shape of a globe or any other suitable shape, and is provided withtwo opposite apertures, which are closed by pivoted lids B, which arecurved to form a part of the fire-box when they rest over the openings.The lids are provided with numerous apertures, G, or slots, so that theycan serve as grates. The lids are each pivoted to the firebox at one oftheir ends, and at the other ends are provided with a handle-stud, D,and can be locked in position on the fire-box by means of spring-latchesE, of any suitable construction. The lids are preferably pivoted to movesidewise, but can be pivoted or attached to the fire-box in any othersuitable manner. The fire-box is provided with two opposite projectingpivots, F, journaled in the sides within the stove or heater G, one ofwhich pivots has a squared end to receive a key for rotating thefire-box. The bottom H of the stove or heater G is provided with acircular aperture, J, provided with beveled edges H, against which thecovers or lids can fit so closely that all the draft must pass throughthe fire-box, and cannot pass around the firebox or covers. The fire-boxmay be made larger or smaller, as may be desired.

The operation is as follows: One of the lids B is opened and wood andcoals are placed in the fire-box, and are then ignited, the draftpassing through into the fire-box through the apertures of the. lowerlid B and escaping through the other lid. If the ashes are to beremoved, the fire-box is rocked by swinging the same to and fro by meansof a key on pivot F, provided with a squared end. Then the globe orfire-box is inverted, so that the bottom lid B will be at the top. Ifthis lid is opened, the oinders and clinkers can be removed and freshcoals placed in the fire-box. The fire-box may remain in this positionuntil a fresh quantity of coals is again required. It will not always benecessary to shake the fire-box to remove the ashes, for by overturningthe fire-box the coals, cinders, and ashes in the same will be shaken sothoroughly that the ashes will drop through the apertures of the bottomgratecover. 11? the fire-box must be adjusted higher or lower to fitclosely in the openings J, washers can be placed under the pivotsFFtoraise the same, or the washers can be removed, as the case may be;or it maybe raised or lowered in any other convenient manner.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The combination, with the spherical or globeshapedfire box or chamber, adapted to' revolve, and having the slotted orapertured covers, of the stoveor heater provided in its bot tom with anopening having the upper beveled edge, substantially as herein setforth.

CYRUS K. VILAS.
